"At high Reynolds numbers, the boundary layer separates. Your assumed stratospheric structure has completely collapsed physically. You are using a static pond model to calculate the crest parameters of a tsunami."
Lin Yu stood up and looked down at Zhao Tianyu. "Not only is your mathematical logic inconsistent, but you also lack basic physics knowledge. This piece of writing isn't even worthy of being used as a table leg."
Li Hao was completely confused, but he could see that Zhao Tianyu's body was trembling slightly.
Upon hearing this, Professor Chen lowered his head and opened Zhao Tianyu's paper. After only a couple of glances, Professor Chen's expression darkened.
"That's utter nonsense."
Professor Chen tossed the paper back to Zhao Tianyu, his tone stern, "You haven't even laid a solid foundation, yet you're trying to package yourself with sophisticated vocabulary. Is this the academic rigor of your provincial capital's No. 1 High School?"
Zhao Tianyu held the returned thesis, his knuckles clenched so tightly they turned white, his nails almost digging into his flesh.
His pride and the halo he had accumulated at the exchange meeting were shattered to pieces by Lin Yu in front of the Tsinghua and Peking University professors at this moment.
"Tomorrow's diagnostic test."
Lin Yu put his hands back in his pockets, turned and walked towards the door, completely ignoring the two who were on the verge of collapse. "I hope the test isn't too boring. Otherwise, I'll just have to continue sleeping in the exam room."
The next day at 8:30 a.m. The main teaching building of the winter camp, the first lecture hall.
All 120 top students from across the province were seated. The atmosphere inside the examination hall was oppressive, making it hard to breathe. This preliminary exam would directly determine the initial shortlist for the Tsinghua and Peking University score reduction agreements.
Su Qingwan sat in the middle, near the front, her palms sweaty. She turned to look at Zhao Tianyu to her right.
Zhao Tianyu's back was taut like a bow about to break. Last night, after returning from Professor Chen's room, Zhao Tianyu locked himself in his dormitory, ignoring even when Li Hao knocked on the door.
Lin Yu was still sitting in the last row of the exam room. There was only a black ballpoint pen on his desk, no ruler, no eraser, and even his admission ticket was just haphazardly stuck to the corner of the desk with a wad of transparent tape.
Nine o'clock sharp. The exam bell rang.
The proctors included not only officials from the provincial education commission, but also several professors from the admissions offices of Tsinghua and Peking Universities. Professor Chen personally carried the sealed bag and walked onto the podium.
"This diagnostic test will not be divided into subjects; there will only be one comprehensive paper. The time limit is three hours. The total score is 150 points."
Professor Chen scanned the entire room, his gaze lingering for a moment on Lin Yu's position, his eye twitching slightly.
Try curling your hair.
A collective gasp filled the examination room.
Su Qingwan glanced at the first big question, and her mind went completely blank.
Title: Based on the Lagrange, derive the Hamiltonian canonical equation of a one-dimensional simple harmonic oscillator under damping force and find its phase trajectory.
This isn't high school knowledge; it's core content from university-level theoretical mechanics. This isn't a diagnostic test; it's a brutal, one-sided massacre of high school students.
Zhao Tianyu looked at the exam paper, a cold smile curling at the corner of his mouth.
To prepare for this winter camp, he had thoroughly reviewed all four major mechanics and advanced mathematics textbooks from his freshman and sophomore years. Although the problem was difficult, it was within his knowledge base. He picked up his pen and began frantically calculating on the scratch paper.
The only sounds in the examination room were the scratching of pens on paper and the anxious breathing of the examinees.
Lin Yu looked at the test paper in his hand.
There are ten major questions in total. They cover theoretical mechanics, electrodynamics, the foundations of quantum mechanics, and real analysis.
It was indeed beyond the curriculum. But in Lin Yu's view, the difficulty was no different from elementary school arithmetic problems.
He didn't take any draft paper.
Remove the pen cap and start writing directly in the blank space on the answer sheet.
His movements didn't pause for a moment, not even a pause for thought. His eyes scanned the problem, and his right hand had already produced the optimal mathematical model.
The first question was about the Lagrange quantity. Lin Yu directly used the Legendre transformation to write out the Hamiltonian, and solved the phase trajectory with three lines of formulas.
The third question concerns energy level transitions of microscopic particles in an infinitely deep potential well. Lin Yu didn't even bother to write out the full Schrödinger equation, directly using operator algebra to express the eigenvalues.
Time passed second by second.
When Zhao Tianyu finished the third major question, he looked up and wiped the sweat from his forehead. He glanced at the clock on the wall. 9:25.
His progress was absolutely the fastest in the entire class. He was certain that no high school student could calculate faster than him.
Just then, the sound of chairs being pulled out came from the back of the examination room. The sound was incredibly jarring in the extremely quiet lecture hall.
Everyone looked in the direction of the sound.
Lin Yu stood up. He neatly placed the test paper and answer sheet on the table, picked up the black ballpoint pen, put one hand in his pocket, and walked towards the podium.
Zhao Tianyu's pupils suddenly contracted.
Submit the paper? There have only been 25 minutes since the exam started; there's not even enough time to read all the questions.
"Hey kid, what are you doing?"
A proctor from the provincial education commission frowned and shouted sternly, "The exam time is less than a third of the way through; you're not allowed to hand in your paper early. Even if you can't answer a single question, you still have to sit here and reflect on your actions!"
"Who says I can't do it?"
Lin Yu stopped in front of the podium, his tone as calm as if he were stating the weather today.
Professor Chen strode over and snatched Lin Yu's answer sheet.
The provincial education commission proctor sneered, "Twenty-five minutes to hand in the paper, what else could you be but a blank paper...?"
His words caught in his throat. He saw Professor Chen's hands begin to tremble again.
The answer sheet was filled with meticulously written derivations. There wasn't a single correction, not a single superfluous word; it was as precise as a standard answer printed by a machine. No, it was ten times more concise and elegant than a standard answer.
Professor Chen looked at the last proof problem on real analysis, his voice hoarse: "You...you proved it using Lebesgue integration?"
"The Riemann integral cannot handle such discontinuous functions. The Lebesgue integral is the most fundamental tool."
Lin Yu checked the time. "Can we go now?"
Professor Chen took a deep breath and nodded vigorously: "Okay...you can go now."
The teachers from the Provincial Education Commission stared at Lin Yu as he walked out of the classroom, as if he were a ghost.
The entire examination room was deathly silent for a full minute.
Zhao Tianyu's knuckles turned white as he gripped the pen, and a slight cracking sound came from the pen barrel. He stared intently at the closed door.
Impossible. Absolutely impossible. To finish this university-level exam in twenty-five minutes, unless he memorized the answers beforehand!
Five minutes later, the sound of a chair scraping against the floor echoed in the examination room once again.
Xia Zijing stood up. She pushed up her thick black-rimmed glasses, picked up a stack of used draft papers, and walked to the podium to hand in her paper.
"So...you've finished too?"
